Category Overview
Service valves are critical connection elements at the centre of installation and service work, controlling the refrigerant line between the indoor and outdoor units of split air conditioning systems. Since all operations such as evacuation, refrigerant charging, pressure measurement and isolating the system are carried out through these valves, quality and reliability directly affect the life of the air conditioner. In the Yedepa.com Service Valves category, models with forged brass and copper bodies, high pressure resistance and valve caps have been brought together. You can find, under one roof, parts that professional air conditioning technicians and technical service companies can use with confidence both in new installations and for maintenance/replacement needs.
Products You Can Find in This Category
The category covers service valve options in different diameters, suitable for the copper tube sizes most in demand on the market. All models are compatible with R22, R410A and R32 refrigerants, manufactured with a forged brass + copper combination and resistant to high pressure conditions. Some of the frequently preferred product types are as follows:
- 3/4" Split Air Conditioner Service Valve — ideal for the gas line of large-tonnage and VRF systems, forged brass body and capped valve design
- 5/8" Split Air Conditioner Service Valve — widely used on the suction line of 24,000–36,000 BTU split and multi systems
- 1/2" Split Air Conditioner Service Valve — the most preferred size for the gas/liquid line of medium-tonnage air conditioners
- 3/8" Split Air Conditioner Service Valve — suitable for the liquid line connection in 9,000–18,000 BTU air conditioners
- 5/8" Air Conditioner Service Valve FJ-8887-DG13 — for technicians looking for an original equivalent by specific code reference
Selection Criteria and Tips
The first point to consider when choosing the right service valve is the exact match between the copper tube diameter and the inch size of the valve. Choosing the wrong diameter leads to leaks when tightening the flare nut and to refrigerant loss later on. The second critical point is the body material: the forged brass and copper combination offers a far more durable and leak-tight structure than cast brass. The valve cap coming with its original seal is important for long-term leak-tightness. In addition, the refrigerant type (R22, R410A, R32) and the working pressure of the valve must be compatible; models with high pressure resistance should be preferred especially for R410A and R32. Paying attention to the correct tightening values with a torque wrench during installation and keeping the service port clean also extend the life of the valve.
